The growth of gold nanoplates have been carried out at temperature of 28-30oC in the presence of a binary surfactant mixture: CTAB (cetyl trimethyl ammonium bromide) and PVP (poly-vinyl pyrrolidone) with their various concentrations. Characterizations of the samples have been carried out by using UV-Vis spectroscopy, XRD and FESEM. UV-Vis spectra showed that the gold particles have grown with a various geometrical forms, such as spherical and others. XRD results informed that the presence of two peaks at 2θ: 38.195o and 44.393o indicated the gold-nanoplates, with their crystal orientation of (111) and (200). FESEM images showed the edge-length size of nanoplates was dominated in the range of 11 nm to 50 nm, with a various of morphology nanoplates, such as hexagonal, truncated hexagonal, triangular, square and spherical shapes.enBiner-surfactantsGold- nano crystalSolid substratesSYNTHESIS AND CHARACTERIZATION OF GOLD NANOPLATES ONTO SOLID SUBSTRATES BY SEED-MEDIATED GROWTH METHODUR-Scientific Work Lecturer
